There's one person who has been present at every Real Housewives reunion ever: Andy Cohen. The Watch What Happens Live with Andy Cohen host has served as the moderator of these epic events since Real Housewives reunions first became a thing, and he's been in that position ever since.

So which reunions have been the most difficult for Andy? "Toughest reunion I ever sat through, probably those early years of Jersey where it was blood warfare," Andy said during an audience Q&A at the WWHL For Your Consideration Emmys event in New York City on May 20. "There have been one or two Atlantas where Nene [Leakes] was not feeling it that were tough."
